问题 How do you implement a multiselect combobox as part of a Ext.FormPanel using ExtJs? I've been looking, but can't seem to find a solution that is compatible with the latest version of ExtJs (this question is similar, but doesn't have a working/current solution).

问题 ExtJS has a very useful layout mechanism called flex. It works by summing all the things on a row or in a column. Then the space is parceled out using the flex value divided by the sum of all the flex values. This results in a layout like below: The Red box is an hbox layout, the blocks E and F have the given flex values that sum up to 3, so E gets 1/3 the width of the screen, and F gets 2/3rds. The Blue box is another hbox layout, where all 4 pieces (A-D) have the same flex so each one gets

问题 I am trying to set up my ExtJS 4 project so I have three top level applications, for example, /foo/app.js /bar/app.js /baz/app.js Each 'top level' application is a separate ExtJS application, each with their own loaders.

But I thought there should be an easier way - something like adding an href attribute like in menu item. Some ideas? 回答1: There's also an existing user extension that does exactly this. 回答2: That's the way it's done...

问题 In ExtJS, is it possible to have the label of a textfield optimally sized to fit its text in one line? The labelWidth property doesn't have an auto setting, and leaving it out completely has same effect as specifying the default value 100, which will cause a lengthy text to break over multiple lines: http://jsfiddle.net/Qbw7r/ I would like to have the label just as wide as it takes to contain the whole text without wrapping, and the editable field fill up the rest of the available width. 回答1:
